[cairo] Image will not rotate

[Evan White]

I am current building an app that will be a replacement for your 
vehicles instrument cluster as my senior design project.  This app 
allows the user to load custom skins based off PNG images.  Each gauge 
is stored in a list.  When updating the interface the system searches 
the list and fines the gauge fine.  It generated the correct angle given 
input value.  The problem is that it does not rotate the image at all.  
The dashboard class is the controller for exposing the window and the 
analog class is where the actual image is being processed and rotated.  
I am not a computer science major I am an electrical engineering one so 
please mind the poor programming practices that are used in the code.  
If you want to make suggestions that would be great, but I have no clue 
why my image is not rotating.
